1. The nucleus x , which is essential for function and survival of the
x x x x x x x x x


cell.
x



A) is the site of protein synthesis
x x x x x



B) contains the genetic code x x x




C) transforms cellular energy x x




D) initiates aerobic metabolism x x



2. Although energy is not made in mitochondria, they are known as
x x x x x x x x x x


the power plants of the cell because they:
x x x x x x x x




A) contain RNA for protein synthesis.
x x x x



B) utilize glycolysis for oxidative energy.
x x x x




C) extract energy from organic compounds.
x x x x



D) store calcium bonds for muscle contractions.
x x x x x



3. Although the basic structure of the cell plasma membrane is formed
x x x x x x x x x x


by a lipid bilayer, most of the specific membrane functions are
x x x x x x x x x x x


carried out by:
x x x



A) bound and transmembrane proteins.
x x x




B) complex, long carbohydrate chains. x x x



C) surface antigens and hormone receptors.
x x x x




D) a gating system of selective ion channels.
x x x x x x




4. To effectively relay signals, cell-to-cell communication utilizes
x x x x x x


chemical messenger systems that:
x x x x




A) displace surface receptor proteins. x x x




B) accumulate within cell gap junctions. x x x x




C) bind to contractile microfilaments.
x x x



D) release secretions into extracellular fluid.
x x x x




5. Aerobic metabolism, also known as oxidative metabolism, provides energy
x x x x x x x x

,by:
x

, A) removing the phosphate bonds from ATP. x x x x x



B) combining hydrogen and oxygen to form water. x x x x x x




C) activating pyruvate stored in the cytoplasm.x x x x x




D) breaking down glucose to form lactic acid.
x x x x x x




6. Exocytosis, the reverse of endocytosis, is important in
x x x x x x x into
the extracellular fluid.
x x x




A) Engulfing and ingesting fluid and proteins for transport
x x x x x x x




B) Killing, degrading, and dissolving harmful microorganisms
x x x x x



C) Removing cellular debris and releasing synthesized substances
x x x x x x




D) Destruction of particles by lysosomal enzymes for secretion
x x x x x x x



7. The process responsible for generating and conducting membrane potentials
x x x x x x x x


is:
x




A) diffusion of current-carrying ions. x x x



B) millivoltage of electrical potential. x x x



C) polarization of charged particles. x x x




D) ion channel neurotransmission.

8. Epithelial tissues are classified according to the shape of the cells
x x x x x x x x x x


and the number of layers. Which of the following is a correctly
x x x x x x x x x x x x


matched description and type of epithelial tissue?
x x x x x x x



A) Simple epithelium: cells in contact with intercellular matrix;
x x x x x x x


some do not extend to surface
x x x x x x




B) Stratified epithelium: single layer of cells; all cells rest on
x x x x x x x x x


basement membrane
x x




C) Glandular epithelium: arise from surface epithelia and
x x x x x x


underlying connective tissue
x x x




D) Pseudostratified epithelium: multiple layers of cells; deepest layer x x x x x x x


rests on basement membrane
x x x x



9. Connective tissue contains fibroblasts that are responsible for:
x x x x x x x



A) providing a fibrous framework for capillaries.
x x x x x




B) synthesis of collagen, elastin, and reticular fibers.
